Hi,

your input seems to have an invalid encoding, with unreadable characters. Databases are usually quite strict on only accepting correctly encoded input.
Look again at your import process. Where are the data coming from? Is it possible that you're importing them with a wrong encoding setting? Are you using Unicode, UTF-8, or a locale-specific encoding?

If you can't fix the input and need the characters as they are, you could use "Encode URL" (when writing) and "Decode URL" (when reading from the database) to create a representation of your text that the database accepts. This is how it would look like inside the database:

NEW+YEAR+SALE+%EF%BF%BD%EF%BF%BD%EF%BF%BD+TAKE+OVER

Best regards,
Balázs
